SPECIFICATION forming part of Letters Patent N0. 773,269, dated. October` 25, 1904. Application liled December 6, 1902. Serial No. 134,162. (No model.)

To @ZZ whom it may concern.:

Be it known that I, WILLIAM VANDEEMAN, a citizen oi' the United States, and a resident of VVillimantic, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Fireproofv illustrated in the accompanying drawings, in-

Figure lis a perspective view in sectionthrough a box embodying my improvement.

Fig. 2 is a view in section through a part oi". the box, showing the means of protecting the joint at the point where the cover and sides Fig. 3 is a like View showing a modi-` meet. iied form of the improvement. Fig. 4 isa detail View showing the upper edge of the front ofthe box. Fig. 5 is a detail view showing a sheet of the packing.

It has been found that there is a want fora box in which papers and the like may be stored and be safe to a greater or less degree from injury by lire.

ment, for the reason that they are too heavy and bulky. In order to provide the requisite structure, it has been found that a receptaclemay be constructed of sheet metal which will In the draw'- vided with means whereby papers or theA like contained in the interior may be shielded fromy fire to a greater or less-extent.

In the form of construction of the ireproof box which embodies my invention it is nec Sat'es of the ordinarypattern and structure do not lill this require' low the insertion of these filling-pieces.

tom, and back of the box. This sheet is bent to the proper form, as shown in Fig.l ofthe drawings. Separate pieces are united to this sheet, forming the outer end walls. The outer end walls are joined to the sheet forming4 the outer wall of the sides and bottom, as by angle-irons 3, rivets being employed for this purpose. Angle-irons 4. may also be placed on the corners at the ybottom to support the structure at this point Aand also to afford a finish. Strips 5 may also be placed around the top'of the sides and end to form a support and also a finish `for this part of the box.

A lining 6 is then placed within the structure,

this lining being composed of a iireproof material formed in sheetsl of a size equal atleast to the dimensions of the sides, bottom, and ends of the box. In the construction of these devices it has been found thatasbestos-board, which is comparatively stiff, meets the requirements. These sheets are placed in proper position in the box, and the inner wall 7 is then placed in position., This wall may consistoil a single piece of sheet metal forming the inner wall of the front, back, and bottom 'of the box, and the asbestos lining which has been placed in position and of the required thickness will form a proper support for this inner wall. The inner walls 8 of the ends are Vformed of sheets of metal, as in the case of the outer wall. l VA Vfilling piece or finish 9 is then placed between the sheets form-ing the outer and inner walls of the box, if desired, in

this instance the sheets of asbestos forming the sides and ends terminating at such distance below the top edge of the box as to elll- T ie rivets for securing the filling-pieces 5to the front wall may pass entirely through the box, if desired, as shown in Fig. l, thus holding the filling-pieces in place and also firmly uniting the outer and inner walls of the box.

.The rivets uniting the angle-irons to the bottom and end corners may, it' desired, pass through both the outer and inner walls of the box'or only through the angle-iron and that wall to which it is secured. A groove 10 may be formed in the filling-piece .9,ii1 desired, for the reception of a packing or the like to be hereinafter described.

IOO

- constructed of sheet metal with a lining of asbestos-board, as above described. In the form of cover shown two sheets 11 and 12 are preferably used, forming the outer and inner walls, respectively. These are united as by means of rivets passing through the angleirons 13, which latter serve as a finish for the box and also extend below the inner surface.

of the cover and form a flange surrounding the upper edge of the box.

A packing 14 is located in the groove 10 in the filling-piece 9. This packing isl constructed of a fireproof material, as asbestos', and in the preferred form of the invention, as shown inthe drawings herein, is of tubular form, as clearly shown in Fig. 4 of the drawings. This packing is preferably secured in the groove 10, and the tubular form provides an air-space in the packing, as well as providing means whereby the joint between the upper edge of the box and the cover is ompletely packed against the passage of In Fig. 3 of the drawings I have shown a modified form of theinvention in which an inner metallic plate 15 is inserted, the space between this inner plate and the outer plates being occupied by asbestos cloth or the like. i

The packing in the form of invention shown in this figure consists of a sheet of asbestos cloth doubled back upon itself in such manner as to form a loop or tube 16 at the inner edge, against which the cover may press when it is closed to securely pack the joint between the upper edge of the box and the cover. The body of this packing', formed Aof the two parts 17, which lie against each other. project downward into the box, being secured between the plates forming the same. As shown in said Fig. 3, this'packingis located between the outer plate 1 and the filling-piece 19, the rivets securing these parts together passing through this packing.

It is obvious that the details of construction may be varied to a considerable extent without departing from the scopeof the invention and that the precise form of the sheets forming the sides and ends of the box as herein shown need not be adhered to, and the form of uniting the several pieces and location of the rivets for accomplishing this need not be strictly followed, as these forms may be departed from to a considerable extent within the skill of the ordinary mechanic.
